*** STOP: 0x000000ED (0x8A691C08, 0xC0000006, 0x00000000, 0x00000000). (Caught it in a video) After this Windows tries to start, and then the computer ends up back at the screen where the options are "start Windows normally, safe mode, safe mode with networking, etc. It will continue doing this until the computer is shut down.
When I run the diagnostics the DST Short Status Test fails, with error code 1000-0146. I replaced the original hard drive about a year ago, as you suggested in topic http://www.geekstogo...-e/page__st__15 and everything has worked fine until now. I did reseat the hard drive, to no avail. I made a boot disc, and when I selected "R" to repair, it said to type "exit" to end the session, and then the prompt would appear, with no other choices. Thanks very much for your time and consideration.
